Detroit Lions running back Kerryon Johnson sprained his knee Sunday but doesn't need surgery and will be week-to-week, a source told ESPN's Adam Schefter.

Reports this afternoon now list Johnson as out for Week 12, which isn't a surprise considering it's a short week. Johnson has 103 carries for 554 yards and two touchdowns along with 30 catches for 203 yards and a touchdown. Prior to the injury, Johnson had 15 carries for 87 yards and a touchdown along with two catches for 10 yards against the Panthers. Riddick and Blount will most likely handle a majority of the RB duties in Week 12. He may have a chance to play in Week 13.
